The first one is 15.75 lbs or 15 3/4. The second one is 28 years old. The third one is$9.90 each t-shirt

Step-by-step explanation:

For the first one you multiply 18 by 14 and you get 252. Then there is 16 ounces in a pound so you divide by 16. Then you get 15.75. So that is your answer. The 2nd one you take 84 and multiply it by 1/6 then since she is twice the age of her sister you multiply by 2. so it would look like: 84 times 1/6= 14

14 times 2 = 28. So she is 28 years old. The third one you take 32 and subtract it by 12.20. You will be left with 19.8. Then both t-shirts cost the same so you would divide 19.8 by 2. You are left with 9.9. So the answer is $9.90. Sorry this took 10 minutes.

15.75lb of hotdogs

Amy is 28 years old

she paid $9.90 for each shirt.

Step-by-step explanation:

1) we multiply the number of packages by how much each package weighs. which gives us 252ounces we can then convert ounces to pounds by multiplying by 0.0625pounds/1ounce which gives us 15.75lb

2) amy's age is her fathers age devided by 6 which gives us fourteen. we know Hannah's age is twice Amy's age, so we multiply 14 by two, 14X2=28

3) we subtract the money Rose spent on the poster from the overall amount rose spent. $32.00-$12.20=$19.80. so we know Rose spent $19.80 on t-shirts, since we also know she bought two equaly priced t-shirts we can devide $19.80 by 2, $19.80/2=$9.90, therfore, she spent $9.90 on each shirt.
